Adam buys some stickers for his friends.
If he gives each of them 4 stickers, he has 16 stickers left.
If he gives each of them 7 stickers, he has 4 stickers left.
- How many friends are there?
- How many stickers does Adam buy?
(a)
Big difference
= 16 - 4
= 12
Small difference
= 7 - 4
= 3
Number of friends that Adam gives to
= 12 ÷ 3
= 4
(b)
Number of stickers that Adam buys
= 4 x 4 + 16
= 16 + 16
= 32
Answer(s): (a) 4; (b) 32
